Kacha.
The sound of an eggshell breaking rang out.
Jiang Yu had broken through.
The breakthrough of a Demon Trainer was just like what was written in some fantasy novels. It required time to accumulate, and the feedback from contracting a Demon Seed was a special feature of this system.
However, there were nine minor realms in each major realm of the Demon Trainer.
For each realm, a Demon Trainer could only contract two Demon Seeds at most. It was impossible to break through nine minor realms and reach the next major realm in the time it took to contract two Demon Seeds.
When ordinary Demon Trainers broke through when they contracted a new Demon Seed, there was a 90% chance that they could only break through one realm.
Furthermore, the higher the realm, the harder it was to break through.
Even if it was above platinum, it might not be possible to break through successfully. It would only increase the accumulation for the next breakthrough.
Jiang Yu's aura rose.
His realm had broken through from 5-star Black Iron Rank to 6-star Black Iron Rank.
However, Jiang Yu did not open his eyes. He continued to break through.
The mana feedback continued to grow, and the Origin Sutra was still circulating.
"It's a little difficult. At most, I can only break through once more, but it's enough.”
Jiang Yu felt the growth of the magic power in his body. He muttered in his heart and focused on breaking through.
Kacha.
Vaguely, Jiang Yu heard a voice again.
His realm rose again.
It had reached 7-star Black Iron rank.
But it also stopped here.
He could not continue to improve.
The last time he contracted the Desert Giant, he had broken through from 1-star black iron to 5-star black iron. This time, he had only broken through to 7-star black iron.
From this, it could be seen that the higher the realm, the more difficult it would be to break through.
"Phew."
Jiang Yu exhaled a mouthful of turbid air and opened his eyes. A bright light flashed in his eyes. He stood up and stretched his body. Then, he punched out, and the sound of air being torn apart immediately sounded.
"It's time to leave. I still have to find some metal for the Origin Warriors to devour.”Jiang Yu murmured.
Mechanic Magic Seeds could also be injured, but it was easier for Mechanic Magic Seeds to recover after being injured. They could devour metals or minerals to recover.
It was simple.
But it was difficult.
After all, there were some places that didn't have that much metal for you to devour.
Some metals were not cheap to buy.
Therefore, there were not many Demon Trainers who contracted Mechanic Demon Seeds, and ordinary people could not afford to raise such Demon Seeds.
Fortunately, there were quite a lot of metals in the ruins. However, Jiang Yu reckoned that he should pay more attention to the Origin Warriors in the future to prevent them from getting too injured.
At least until he became rich.
Well, of course, the Origin Warriors were used as trump cards in Jiang Yu's original plan. He probably wouldn't have many opportunities to make a move. Moreover, for Jiang Yu at this stage, the most important thing about the Origin Warriors was their investigative ability.
"Tsk, speaking of which, my current Mechanic resources should be enough for the Origin Warrior to evolve. However, the Origin Warrior is injured now, so I have to wait for a while.”
When the Demon Seed was injured, it could not evolve.
This was because there was a high chance that the evolution of the Demon Seed would fail. During the evolution, the energy contained in the resources would be too large, and the injured body would not be able to perfectly control this energy. As a result, it would suffer a backlash, causing even more serious injuries. It might even damage the foundation of the Demon Seed, causing it to be unable to evolve again.
Therefore, after thinking about it, Jiang Yu gave up on the idea of evolving the Origin Warrior.
Shaking his head, Jiang Yu recalled the Desert Giant and looked at Tyrant. "Let's go, Tyrant."
Since the Search Card was still active, Jiang Yu decided to continue strolling around the ruins to see if he could find anything good.
The two of them left the secret chamber deep underground.
However, perhaps it was because he had obtained too many good items in the ruins, Jiang Yu had not encountered anything good when he left the ruins. However, he had obtained three sets of Black Iron Rank resources for the Mechanic class. They were not very precious and could only be considered ordinary, but they could still be sold for a good price.
After all, the evolution resources of the Mechanic class were considered to be one of the few. They were relatively rare, so the price was relatively higher.
They left the ruins.
Looking at the ruins of the city behind him, Jiang Yu shook his head. He looked at the desolate plains in front of him and murmured. "It's time to go to other places. In a few more days, I should leave this place and return to Tianji City.”
Time passed.
Night gradually descended.
The Earth Fortress was like a desert after nightfall. The temperature dropped significantly, making people feel a little cold.
Jiang Yu followed Tyrant as they stepped into the mountainous region and headed in a certain direction, searching for the last suitable resource for the Desert Giant's evolution.
There were still two hours before the Search Card ended.
Jiang Yu naturally had to hurry.
He even planned to leave the mountain region and head to the desert region to take a look.

Jiang Yu looked helpless as he listened to the notifications.
If it was in the past, he would not reject these things. After all, he could sell them for money even if he did not need them.
But now that the Search Card was about to end, he still wanted to find the last evolution resource for the Desert Giant. Where would he have the time to dig for these things?
Suddenly.
The notification sounded again.
